Leak-proof engineering supplies a range of packings. 7300/7302 are specification type of the braided ptfe packings. These braided ptfe packings are made of pure ptfe yarn through braiding. Various characteristics of the braided ptfe packings include: excellent anticorrosion, good self-lubrication and non-sticking, therefore, braided ptfe packings possess not only good flexibility and resilience but also very excellent anticorrosive property. All types of chemical media are resist by them.
